Snow Formation: Crystal Growth and Precipitation

This lecture covers the formation of snow crystals in the atmosphere, starting with the record snowfalls in various locations. It delves into the composition of the atmosphere, air pressure, vapor pressure, and the properties of air and water vapor. The mechanisms of vapor transport, cloud and precipitation formation, and ice crystal formation are discussed, along with the processes of ice crystal growth and aggregation. The lecture also explores the different types of snow and ice crystals, super-saturation effects on crystal shapes, and the atmospheric conditions influencing crystal growth and modification.
